Quad rod jr knife sharpener

ABSTRACT

The apparatus is an improvement in utility from an old apparatus. This apparatus provides operator two different angles, one angle to be used for large knifes or honing the blade. The additional angle is used for thin blades and realignment of blade edges. An additional improvement is the addition of a shear sharpening apparatus creating a versatile apparatus. An additional improvement is the utility of the housing unit. The housing unit is versatile where the user can mount to a fixed position or can hand-held. No other apparatus exist using this utility.

BACKGROUND OF THE INVENTION

The present invention relates to a manual, one-piece, durable, plastic, (but not limited to plastic), solid-bodied construction knife sharpener, and more particularly, to a knife sharpener that utilizes four each straight, specifically angled, in-line, stationary, 0.156″ diameter, sharpening rods that have been affixed into the knife sharpener's durable, plastic, solid-bodied construction. This manual knife sharpener can be hand held or mounted in a number of ergonomic, stationary positions. There are four each mounting holes and/or hang holes within the body of the knife sharpening unit. When mounting this manual knife sharpening unit in a stationary capacity, only two mounting holes are used at a time. When using this manual knife sharpening unit for hanging, any one of the two, notched holes, positioned on each of the corners by the handle, can be used. The notch is cut down into the body area to allow for easy positioning for a clasp-type attachment.

This manual knife sharpening system has two sets of four each in-line, 0.156″ diameter, sharpening rods to a set, known as a “quad rod sharpening system”. Each set of quad rods has been positioned to be at angles different from one another. The #1 positioned, specifically angled, in-line set of stationary, 0.156″ diameter, sharpening rods has angles that will specifically sharpen thin, flexible knives, along a blade's edge. These sharpening rods can be made of, but not limited to, a hardened stainless steel, tungsten steel, carbide steel, diamond rod or ceramic rod material.

The #1 position is also capable of thinning out the angles on a thicker knife blade, along the angle of that knife blade's edge. Thicker knife blades, that have been properly thinned to angles formed by the #1 positioned, specifically angled, in-line set of 0.156″ diameter, stationary, sharpening rod, can then be further refined to final cutting edge angles prepared within the #2 position, specifically angled, in-line set of stationary sharpening rods.

The #2 positioned, specifically angled, in-line set of 0.156″ diameter, stationary sharpening rods, has angles that properly realign and refine a stiff, thicker, knife blade edge angle, whose angles are different from those of thin knife blades also used to sharpen Scalloped edge, slicing type knife and/or bread knife.

We have the only manual knife sharpening system that can effectively sharpen within the interior radius and total surface area of a scalloped edge's blade length. The four each, 0.156″ diameter quad rods, distribute a more even surface pressure and contact along the length of the scalloped blade's surface, avoiding too much pressure in a given area of the knife blade, when compared to a single set of sharpening rods. A single set of sharpening rods has only two points of contacts, which places too much pressure in a given area of the knife blade's edge, resulting in less refinement, possible tearing, ripple, malformed, jagged blade edge. As a result, the knife edge's microscopic teeth will be malformed, overly thinned, weakened, jagged, missing and/or undefined.

These four each specifically angled. in-line, stationary sharpening rods have been made in a 0.156″ diameter, specifically for the purpose of producing an ultra-fine, microscopic, knife blade cutting edge. An ultra-fine microscopic cutting edge is one that has been properly formed, creating the maximum amount of cutting teeth, which are 500 per length of inch, on a knife blade's edge. Having a set of four quad rods, instead of two, will make it possible to distribute the surface pressure of the knife blade over the four points of contact. By the knife blade's making even, surface contact on all four quad rods, it becomes possible for the knife blade's angle to be perfectly aligned, on a vertical, horizontal and parallel line, when compared to the inconsistencies of a single set of two each sharpening rods, which can pitch in any direction.

This unit also houses a manual Scissor Sharpener.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an improved knife sharpener.

It is another object of the present invention to provide a knife sharpener that is more durable, more versatile, safer, and easier to use in either a hand held or a mounted position.

It is yet a further object of the present invention to improve on the current manual, single rod sharpening system that is either hand held, or mounted. This quad rod, hand held or mounted sharpening unit, will be used within these areas: professional culinary institutes, restaurants, sportsmen, retail professions, the processing industry, (beef, pork, poultry and fish), domestic kitchens, utility purposes, anyone who needs to sharpen and realign a knife blade's edge. Sharpening rods that are controlled to provide optimal angles and pressures and which obtain even and consistent edge realignment and/or edge retrieval, regardless of the sharpening technique being employed by the particular person who sharpens the knife.

It is another object of this present invention to create a durable, low-cost, on-line, knife sharpener for the beef, pork, poultry and fish industries that can be easily mounted, ergonomically, to more specifically accommodate awkward areas that other larger, knife sharpeners cannot fit into. This will also be the only hand held/mountable, quad rod, knife-sharpening unit to be designed for the specific needs of the processing industry.

It is another object of this present invention to put into place the advantages of a quad rod knife sharpening system; one that makes it possible to distribute even amount of surface pressure on the knife blade when positioned within the quad rods' four points of contact, resulting in a more refined, microscopic cutting edge. A traditional, two contact point sharpening rod system, is disadvantageous because it places too much pressure in that given area of the knife blade's edge, resulting in less refinement, especially if used with too much force. Too much force and improper sharpening techniques can tear, ripple and divot a final, knife's edge angle. As a result, the knife's edge's microscopic teeth will be malformed, overly thinned, weakened, jagged, missing and/or undefined.

It is another object of this present invention, that by having a sharpening system implementing a set of four quad rods, instead of two, makes it possible to distribute the surface pressure of the knife blade over the four points of contact. By the knife blade's making even, surface contact on all four quad rods, it becomes possible for the knife blade's angle to be perfectly aligned, on a vertical, horizontal and parallel line, when compared to the inconsistencies of a single set of two each sharpening rods, which can pitch in any direction. (Putting the skill into the sharpening process through unskilled hands means to compensate for lack of skill through design improvements. The quad rod sharpening system was developed to easily keep a knife blade's edge angle in proper alignment and keep it sharp. Labor that is brought into processing facilities and/or professional and institutional kitchens, etc., is mostly unskilled in the art of knife sharpening. The proper and consistent sharpening angles that can be achieved through the quad rod sharpening system, will quickly lend professionalism to those unskilled hands.)

Other features and advantages of the present invention will become apparent from the following description of the invention which refers to the accompanying drawings.

FIG. 3-Side View of Scissor-Sharpening Action

Sharpening Slot for Left-Handed Shears/Scissors

Located on the left side of the sharpening unit, within FIG. 1.D, the two 5/16″ wide×1¼″ long, open, off-set slots intersect to an open center point equaling 3/16″. All of the slotted areas are cut entirely through the ¾″ thickness of the housing material. The scissor-sharpening slot on this side of the unit is used for left-handed shears and scissors. The placement of these open, off-set slots provide the proper shear blade positioning to coordinate the left-handed shear blade angles to match that of the offset, specifically degreed, angled, sharpening rod position, allowing for correct blade edge realignment. To properly begin the shear-sharpening process, start by closing the tips of the shear blades against the surface of the ⅛″ round, specifically degreed, angled rod within the open crossover area at the center adjoining point between the two open 5/16″ wide×1¼″ long, off-set slots. Continuing the process, push the blades forward in a consistent, gentle, even-pressured motion towards the housing unit. Always keep consistent, total surface contact along the total length of the blades' edge surface, continuing all the way through the end of the shear blade. As the blades are pushed into the unit, the blades will spread into a fully opened position.

When pulling the blades out of the sharpening rod area, the shear blade edges should not make surface contact with the sharpening rod. The shear blades can only be properly sharpened in a forward motion.
